The paper deals with the problem of synthesis and analysis for procedures of reliability parameters estimation in case of radioelectronic devices technical state deterioration. The synthesis problem was solved on the basis of the maximum likelihood method. The analysis problem was solved using analytical calculations and based on statistical simulation.
The design and operation principle of the ring antenna array for monitoring are considered. Ring radiators array and signal processing unit diagram that separates the right and left-handed circular polarization field are constructed.
